LIS: COREFUNCTION Flashcards
The three main phases of LIS Corefunction
- Pre-analytical
- Analytical
- Post-analytical
This systemic collection of data greatly improves data
security, facilitates better data validation and prevents
damaged or lost data.
Pre-analytical Phase
what are the 6 definitions of the pre-analytical phase?
The pre-analytical phase:
✓ Reduces log in time
✓ Ensures correct identification of specimens
✓ Creates a database of patients
✓ Creates and maintains a unique specimen ID
✓ Helps identify mislabeled specimens
✓ Barcodes samples
what happens when an error occurs in this phase?
It will affect all the phases after it
Any error that will happen in this phase will affect all the
phases after it is called?
Domino effect
What should The LIS do to the whole lab staff to
make sure a smooth flow of the laboratory’s mission?
provide assistance
What is the purpose of logging in your username and ID?
it is to track who’s the MedTech performing the test on that shift on that specific department
Why do you have to log out if ever you are not in the
department?
If your name is the one that’s logged in and your name is the
one that is there in the paper, let’s say on this task is
performed by (someone) and this would be test that would
really be released in the hospital which means that you are
the one responsible for it. So, if there are any discrepancies
or your results are not accurate, then it would be easy for the
hospital or the laboratory to trace who did the testing of the
sample.
integrating of the barcode in the LIS actually makes the
process________ - _______ for the MedTech to encode the
patient’s name and details manually.
faster; No need
the machine already has a barcode detector wherein if you put the sample in the machine that it then it would _________ reflect on the computer
automatically
When do the MedTechs write the patients details?
the moment they would receive the request that’s when the
MedTech would encode their details in the reception area and
from then it is already recorded in the LIS and it’s for the LIS
to produce barcodes (that includes the patient’s details and
the test requests).
What’s the purpose of the barcode?
- It is also to reduce typographical errors, since MedTechs are
not required to type down there.
Where would your blood go?
Remember that your tubes are where your samples would go
With the barcode, are we still asked to write the patient’s
name and the tube?
Even if you have your bar code already. Yes (write down the
patient’s information), this is to make sure that if the barcode
gets lost or it gets detached from the sample or from the tube,
then we still could identify which specimen belongs to which
patient.
Do you need to write down the patients name, age and gender even if also the date?
It’s important to write the patients details in the sample aside
from sticking the barcode sticker
why is it important to create a database for the patient?
This is to avoid redundancy in the patients’ records.
creates and maintains a unique specimen ID is with the use of?
use of barcodes
specimen ID talks about?
the sample for the test
specimen means?
the sample
Every test will have a ____________, but as for the
patient, they only have _____________
unique specimen ID; one patient ID
The patients will use the same patient ID ________________, but their specimen ID changes ________________
for the rest of their lives; every time they do a test
Allows the staff to generate barcode
barcode sample
arrange in the right order of the pre-analytical phase in the lab
Once the phlebotomist would get the request form, they
will go to the patient, extract blood, and do labeling.
Nurses make their request with remarks
Specimen barcode is scanned in the reception area. The
turnaround time will start. Time will be ticking since it
means that processing is starting already.
Laboratory would receive the request through LIS. LIS
would alert the lab that patient A from room 301 has this
test request.
After blood is extracted, the phlebotomist would transport
the specimen to the lab for processing
The MedTech will tag the request, print it, and notify the
phlebotomist
Specimen will be given to the respective departments
4, 1, 6, 2, 5, 3, 7
it is the term used in the laboratory which means that
they have confirmed/received a request and they will charge
the request in the patient’s account which means that there
will be charges added in the patient’s account (that is for the
payment)
Tag
they are the ones assigned to extract blood
from the patient
Phlebotomist
a mortal sin in the laboratory, since we are
handling the patient’s life.
mislabeling
labelling of blood samples
- last name
- first name
- middle initial
- sex
- age
- date of extraction
- bar code
Enables correct specimen and test identification through use
of pre-analytical data available in the LIS
Analytical phase
Assist in workload management by automated capture of
results from instruments
Analytical phase
Reduces transcription errors from instrument data; Validates results; Assists in QC management
Analytical phase
From the beginning, you have to follow the proper protocol or
SOP’s because?
your analytical phase cannot move forward
without the pre-analytical data.
patient details:
✓ name
✓ gender
✓ birth date
✓ test to be done
✓ ordering physician
How many times will the barcode be scanned?
It depends on the laboratory, but for our laboratory it will be
scanned twice.
What happens during the first scanning of barcode?
First in the reception area, the moment we receive the
specimen
What happens during the 2nd time scanning?
Second by the machine, the moment you would process
the machine, they would scan the bar code
Instruments will ________ result from the machine or
from the analyzers going to the LIS.
directly deliver
_________ since the MedTech will not encode the results
manually
Less errors
LIS checks if result is acceptable since?
since the reference range of the test will be shown in the computer
Abnormal means?
higher or lower than the normal values
Within the analytical phase, the LIS can have an impact on?
process monitoring, workflow, instrument interfacing, and
quality assurance support
The LIS can make ______________________________ for each specimen throughout all of the
laboratory process
sample location and sample status constantly available
It provides ability to monitor workflow metrics such as?
turn around time (TAT)
LIS established rules that ensures?
that users follow proper procedures
can reduce data
transcription errors and
speed up analytic
process
– it means that when a
machine runs the test
then it releases the
result to the LIS directly.
– it’s unidirectional
(follows one line)
one-directional interfacing
may be used by more
advanced
implementations where
the LIS can send data to
the instrument to set up
a run, and results and
QC data are
automatically returned
to the LIS
bi-directional interface
two-way
bi-directional interface
We have the ____________. this is from the receptionist in
the laboratory wherein they would encode the patient’s
data, test request and the barcode will be produced.
test request
From the LIS, the _______- from the receptionist will then
be delivered to the machines or to the clinical instrument
samples
The samples with the bar code will then be fed to the
machine which will eventually produce _________ These
results came from the instrument then, it will automatically
reflect on the information system or the computer.
results
The MedTech will then review the results from the machine
through the computer, validate it, and with the use of the
LIS, the MedTech can then release the __________- and
do the reporting.
results/report
in order to achieve quality assurance
specimen rejections
LIS automatically tracks and generates reports for common QA functions such as?
- Specimen rejections
- Specimen transfers
- Deficiency/corrective action log sheet
- Communication log
- Occurrence Management log
- Analyzer use and maintenance needs
- Instrument and run QC
Focuses on submitting laboratory data to various recipients
based on the purpose of testing
post analytical
Laboratory results can be ________ to patients. We have
healthcare providers and public health officials at sub-national
or national levels.
submitted
Patients ____________ to their results electronically
can have access
In your receipt, they would give you your __________
(usually be patient identification number or last name) and
__________ (identification number).
username; password
they categorize results based on?
the department responsible for the test
